yeah, throw them in a wood burning stove or fireplace. they are high in oils that actually react with the creosote in the chimney and will cause it to flake off thus preventing chimney fires while heating your house. due to the oil, they give off a lot more than their weight in wood (celulose). If you put one in a paper clip and light it you will see ‘jets of fire’ branching out of where it is burning; this is the oil vaporizing and igniting when it comes in contact with oxygen.

Pistachio shells prior to the preparation, namely a good rinse and dry. After you sort by size: large to large, small to small, medium to medium. With the help of a coffee saucer using its diameter, cut out a circle of very thick cardboard (in our case, we used the cardboard from a box).
Outline the center circle and begin with an adhesive to form a flower from the small size of pistachios. Getting glue with four shells in the center, then depending on the size of the shell. And as you can spread mosaic!

Pistachio and walnut shells are often used as a abrasive in a sandblaster to remove paint from surfaces that would be harmed, eroded or scarred by sand or mineral based abrasive. Some vehicle or furniture renovators may be interested.

Synchronicity! I was saving pistachio nut shells and kept going back and forth as to how to best use them. The first comment above answered my question. Thanks. I plan to bookmark this site! Thanks to all.

I’m using them to refill a neck wrap/heating pad (heated in microwave) that my daughter made for her father. Originally it was filled with rice. I’ve seen cherry pits used for the same thing, so I why not pistachios. I scrapped out the center, then rinsed and dried them first.

I did some research a while back on cherry pits. I’m not 100% about using in the way you are, but I know that they release arsenic. I wanted to add to my compost but that was said to be toxic. I know you can make liqueurs so I could be wrong in this instance. Just an fyi.

I haven’t tried it yet, but I think they could be used to refill a bean bag chair. I plan to fill a small bag- maybe an ummatchable sock- and fill as many as it takes to refill the chair. the sock will keep them cushioned and will pad the edges. This will take a while, because, as much as I like pistachios, they are a seasonal treat. Has anyone else done something like this? I don’t like the idea of filling a beanbag chair with anything plastic or styrofoam. What else can they be filled with?

Hi Melinda
Would you like to donate your shells? I can make a good use of them while teaching kids my inventive technique in using them in fine arts. Please let me know contact@efernandes.ca – Cheers and thank you in advance.

I have seen very cute little nut people made using pistashio shells (body,head and maybe shoes) I just can’t remember how they were put to-gether,They sure were awful cute,Maybe 2 1/2 ” high.
Anybody have the directions ??????

Hi Everyone, thanks for posting your ideas on pistachio shells. I am a visual artist and I have developed a technique to make artwork using pistachios shells. Due to their composion, which is hemicellulose, cellulose and lignin, they will last forever, mainly after treating them as of properly. If you wish pls visit my website at http://www.efernandes.ca – My intention is to make of this technique a historical abstraction approach. If you are giving them away, I can certainly collect them as I plan to teach children in schools. Please loet me know. This type of work has been curated by the art gallery of greater victoria, BC and it is now in a competition at the Chelsea International Competition at the Agora Gallery, NY. Let’s jkeep in touch, cheers EFERNANDES

EFERNANDES, What is your address to send shell contributions to? I hardly throw anything out so you’re in luck; I have shells from last year. Good reason to get buy more pistachio’s for the house; love them and can add the shell so what I can send out. I’ll wait for your address. Ellen

Hi Ellen

my addy is: 310-1005 McKenzie Ave, Victoria BC, V8X 4A9 Canada.

Sometimes I capture june bugs which land on my porch and torture them for information as to where their hidden base is. Once they give me the information I want to know I tie them to a pistachio (pronounced: piss-ta-chee-oh) and then add a toothpick and piece of paper (triangle shape) to make a small boat. Next, I wait until it floods on my street and I send them on their way to freedom.

I throw them onto my path in my fernery. They tend to keep down weeds. Nutshells make pretty good mulch and path spreaders and I put them into pot plants as mulch too. But don’t put sharp ones on your path unless you like a bit of pain.

Hi All Pistachio Lovers:
I am looking for pistachio shells donors. Can u donate the empty shells for me. I will use them to prepare a workshop for kids.
You may contact me directly at efernandes@hotmail.ca
Please let me know.

Hello Everyone
I am a fine art painter for more than 13 years in Canada. I, 2 years ago, discovered that pistachio shells should be the substrate for my creative artwork. On average I use 800 shells to build a canvas. I invite you to visit my website, hoping you will love it. It is my thank you to Mother Nature for its unspeakable beauty. If you are looking to donating the shells I will appreciate your collaboration with my work.
Cheers

It the pistachio were salted, I wouldn’t use spread them around the garden,a s salt can hurt plants. Or at least, I would soak them in a bucket of water really thoroughly before using them.
Same goes for putting them at the bottom of plant pots.

They can lift your old bathroom into a sanitary with modern and elegant designs and various fixtures.
By knocking out the wall you can create a space in small bathrooms
but it is not always possible. Hopefully the sections above have contributed to your understanding of major bathroom remodeling.

If you’d like to donate your pistachio nut shells in order to prevent throwing them out, I’d love to give them a good home, literally . I’d like to make pet houses, natural mosaics to teach my class about recyling, and cultural fun vests. please contact me @ naturegirlextreme@gmail.com to donate. Thank you.

By sheer coincidence I found they make a good stuffing for a neck pillow- Sort of like buckwheat hulls if you are familiar with soba makura. You fill a one liter cylindrical plastic bottle (2 liters are too large) with shells, and then use them as a core for a neck pillow. I found that it provides just the right firmness. I imagine other hard granular organic shells or seeds would also work, but this I found out by accident while going through a bag and using an empty seltzer bottle to collect the shells.
